STRAIGHT ANSWERS
- Can I switch straight over?
- Go gradually. Over about 7 days, mix a little more Bully Max into the old food each day until the bowl is all Bully Max. Because 30/20 is denser (535 calories a cup), feed by calories, not by the old scoop: a 50 lb dog needs about 2.1 cups a day.
- IAMS is cheaper per meal. Why pay more?
- A few cents a meal buys 155 more calories in every cup. For a 50 lb dog that is 2.1 cups a day instead of 3.0, 28 days per 15 lb bag instead of 20, and roughly 13 bags a year instead of 18. On the comparison, IAMS Adult Minichunks is $0.77 a meal and 30/20 Chicken is about $1.00 ($0.90 with Subscribe & Save). Cost footnote.
- Which IAMS formula is this compared with?
- IAMS Adult Minichunks, the IAMS formula on the Bully Max brand comparison, at 380 calories a cup. The comparison lists it as containing chicken. Bully Max 30/20 Chicken is 535 calories a cup, and its protein comes from chicken meal, whitefish meal and egg.
